Voriconazole Impurity 50 CAS 79-03-8 chemical structure

Description

As a certified reference material (CRM), Voriconazole Impurity 50 meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.

Voriconazole Impurity 50 (CAS 79-03-8) is a certified pharmaceutical impurity reference standard with the molecular formula C3H5ClO and a molecular weight of 92.52 g/mol.

The molecular framework of Voriconazole Impurity 50 (C3H5ClO) is characterized by a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

Recommended for quantitative analysis by HPLC, GC, LC-MS/MS, or GC-MS as an external calibration standard; it can also be used for spiked-recovery experiments, LOD/LOQ determination, and LC-MS/MS multiple-reaction-monitoring (MRM) calibration.
